File ➡ Save As Other ➡ Optimized PDF ➡ Advanced Optimization ➡ Audit Space Usage. There are three ways to find this tool in Acrobat. This information will help you determine exactly which parts of your file need to be optimized. It breaks down your document so you can see how much space each element takes up. #HOW TO REDUCE SIZE OF PDF FOR EMAILING PRO#
Export PDFs with a dedicated PDF editorĪll major PDF editors come with the ability to reduce PDF size in a few simple clicks.Īcrobat Pro has a nifty feature for PDF file optimization. Using “Save As” allows the editor to create a new file that’s clean and optimized. The result is a larger file size that grows every time you click “Save.” When you make changes or add new content to your document and click “Save,” your editor appends those changes to the end of your file. So, the original PDF file you created remains intact, including its file size. However, “Save As” always creates a new file whereas “Save” adds whatever changes you make to the original. Sure, they both have the ability to create new files on your device. The “Save” and “Save As” functions in many applications are different. Our first method to compress a PDF is by using the ‘Save As’ button, and here’s why. You can use as many of these methods as you want.
Remove unwanted objects in your PDF document. Use your PDF editor’s advanced optimization settings. Audit the space usage of your PDF document. Use a PDF compressor to reduce file size. Export PDF files with a dedicated PDF editor. Here are 7 different methods you can use to compress a PDF, we’ll go through each of them below: 7 easy & advanced ways to reduce PDF sizeħ easy & advanced ways to reduce PDF size. Since the PDF Review Module displays PDF files as they would appear on press, it makes sense to perform preflight and fixes before proofing.Īutomated PDF optimization keeps files clean and consistent throughout a workflow leading to repeatable, expectable results at output. With the PDF Review Module integrated into a Switch flow, you can position the optimization prior to automated online PDF proofing. Clean PDF files will contribute to simplified online proofing. .png "how to reduce size of pdf for emailing")
Optimize PDF files as early in a workflow as possible for better performance and efficiency of downstream processes. Adding that process to the same Action List combines all the PDF optimization into one click or can be automated with PitStop Server. PitStop Pro recently added the ability to rasterize complex vectors, which will also contribute to improving output performance.
Clean-Up (Document structure, invisible objects, workflow data)Īll of these individual Actions are available in PitStop Pro and can be built into one Action List for optimizing PDF file size and reducing complexity. Discard User Data (attachments, empty layers, dictionaries). Discard Objects (metadata, form fields, JavaScript). Remove objects completely outside of the media box. The order in which optimization occurs is this: An in-depth look at what this Action List is doing reveals more than image resampling. For example, this A5 card is being plated at 133 lines per inch, so continuous-tone images are going to be optimized to 266 ppi.Īfter running the Optimize PDF Action List on the file, the size is reduced from 2.78 MB to 1.68 MB. Paying specific attention to the images section, the resolution down-sampling can be edited to meet custom specifications. Especially when you consider that jobs can also be bogged down with complex vectors, as well.Īlso shown above is an Enfocus PitStop Action List used to optimize PDF files. But if a client supplied a 500-page PDF file that was already data merged for mailing, it becomes a big deal quickly. The effective resolution is 400 ppi, which is overkill for this A5 card. This page contains an image that is oversized. And it will presume that each print shop knows what image resolution it requires for plate making or digital output. This article will avoid discussing ppi vs dpi and let that argument lie. This has changed over the years, especially when considering making plates versus digital print. 
When we got out into the real world, the rule of thumb for image resolution used to be, make the ppi two times the dpi. In training, we were taught that an image had to be 300 ppi at 100% to be printable. However, there are also instances where PDF file sizes are very large due to extra data and images that are of a higher resolution than necessary. Print production teams are often faced with images with resolutions that are too low to reproduce with acceptable quality.
